Resumo: | This work aimed to study the genetic variability, to estimate genetic and phenotypic parameters predict genetic values, establishing genetic correlations between characters and construirum selection index of individuals of guarana (Paullinia cupanavar. Sorbilis) in an experiment conducted in Maués, Amazonas. Thirty eseis progenies were evaluated for 10 morphological characteristics, including resistance to anthracnose disease and witches and fruit production in three consecutive years in experimental design of randomized blocks with two replications and six plants per plot. The variance components, and genetic and phenotypic parameters were estimated by the procedure REML / BLUP. There phenotypic and genetic variability among progenies for fruit production, which can be exploited in the breeding program. The genetic gains obtained in this study indicate a larger gain than the clonal selection. The selection of individuals for seed production and composition of the population of improvement should be evaluated for four more years. This work aimed to study the genetic variability, to estimate genetic and phenotypic parameters and predicting breeding values of individuals of guarana (Paullinia cupana var. Sorbilis) in an experiment conducted in Maués, Amazonas. Thirty-six families were evaluated for 10 morpho-agronomic characters, including resistance to anthracnose disease and witches and fruit production in three consecutive seasons, an experimental design of randomized blocks with two replications and six plants per plot. The variance components, and genetic and phenotypic parameters were estimated by the procedure REML / BLUP. The strategy of selecting progenies involving all morpho-agronomic traits proved to be more efficient in regard to genetic gains of 100% and should be adopted in the breeding program of guarana. Moreover, the selection of individuals to seed production and breeding population composition must be further evaluated for over four years since the present genetic gain, ranging from 1.38% to 2.58% did not allow taking a safe decision. |

Trinta eseis progênies foram avaliadas para 10 caracteres morfoagronômicos, incluindo resistência às doenças antracnose e superbrotamento e produção de frutos, em três safras consecutivas, num delineamento experimental de blocos ao acaso, com duas repetições e seis plantas por parcela. Os componentes de variância, parâmetros e valores genéticos e fenotípicos foram estimados pelo procedimento REML/BLUP. Existe variabilidade fenotípica e genética entre as progênies para a produção de frutos, que pode ser explorada no programa de melhoramento. Os ganhos genéticos obtidos neste trabalho apontam para um ganho maior do que o da seleção clonal. A seleção de indivíduos para produção de sementes e composição da população de melhoramento deve ser avaliada por mais quatro anos.

Por outro lado, a seleção de indivíduos para produção de sementes e para composição de população de melhoramento deve ser mais bem avaliada, por mais quatro anos, pois os ganhos genéticos atuais, variando de 1,38% a 2,58%, não permitem uma tomada de decisão segura.Universidade Federal Rural da Amazônia/UFRA2011-05-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/41Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 53 No 2 (2010): RCA; 123-130Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 53 n. 2 (2010): RCA; 123-1302177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
